In addition, since the screws 10a and 10b need only be formed in the area occupied by the openings, they can be applied to the fasteners of small diameters, and the limitation of the cap 1 design can be avoided. In addition, since the opening scheduled portion 4 is integrated with the overcap 3 after the opening plug 2 is opened, the opening scheduled portion 4 does not need to be disposed of after opening, and does not need to be treated at a table, for example.

Cap, Container with Lid

Description

Container with cap and lid {CAP AND CONTAINER WITH CAP}

This invention relates to the cap formed in the inlet part of a bottle-shaped container, and the container with a lid provided with such a cap.

As a cap of a bottle-shaped container, it is generally known to combine the sealing plug and the overcap which is an upper lid (for example, refer patent document 1). In such a cap, after the overcap opening, the pull ring attached to the fastener is pulled obliquely in the opening direction to open the opening.

Moreover, the bottle cap which has a raw material accommodating part which accommodates raw materials, such as powder, removes the bottom lid of a raw material accommodating part with opening operation, and releases a raw material in a bottle is known (refer patent document 2).

However, with regard to the former cap, the pulling method of pulling the pull ring may be greatly different depending on the user who is a consumer, and the pull ring may come off from the breakable portion such as the weld at the time of opening, that is, the opening, and the opening may not be possible. There is this.

In addition, when the score portion is thickened, for example, to prevent pinholes in the score portion, the opening strength is increased, and opening is difficult for a child or an elderly user. In addition, when the size of the pull ring is secured enough to accommodate the fingers of various users, it is not suitable as a fastener of a small diameter, and the design of the entire cap is also limited. In addition, the pull ring remaining after opening is usually an unsightly unnecessary substance and needs to be treated from a table or the like.

In addition, about the latter bottle cap, when it is not necessary to discharge a raw material into a bottle at the time of opening, or when it becomes unnecessary, a bottle cap becomes longer than necessary by a raw material accommodating part. In addition, the user may not like the bottom lid remaining in the bottle because the bottom lid always falls into the bottle. In addition, for hygiene reasons, it is necessary to sterilize the entire bottom lid in advance.

And an upper lid having a screw engaging portion capable of attaching and detaching, and an opening means for forming an opening by separating the separating portion from the plug according to the rotational operation of the screw engaging portion.

In the cap, the inner plug and the upper lid can be detached by the rotational action of the screw engaging portion, and the opening is formed by separating the separating part from the inner plug, for example, with the rotational motion, so that the opening is relatively simple. The opening (in other words, the opening of the fastener) can be reliably performed. In addition, since the pull ring is not used at the time of opening, the situation in which the pull ring is broken and becomes unopenable does not occur. In addition, since it is not necessary to secure a size enough to fit a finger as in the case of using a pull ring, even a small-diameter fastener is not limited in design.

Moreover, as a specific aspect of this invention, a separation part is an opening plan part isolate | separated from an inner plug. In this case, the separating portion is detached from the plug as an opening scheduled portion formed integrally with the main body portion.

Moreover, as a specific aspect of this invention, an opening means includes the 2nd screw member which displaces an opening predetermined part with respect to the outer side part of the said opening predetermined part by screwing with the 1st screw member formed in the opening predetermined part. In this case, since the first screw member formed in the opening scheduled portion and the second screw member which is the opening means of the upper lid are screwed to separate the opening scheduled portion, a member such as a bottom lid is not dropped and left in the container body. Do not throw garbage after opening.

Moreover, as another aspect of this invention, while a 2nd screw member is a male thread with respect to a female thread, a rotational operation for operating an opening means is carried out in the opposite direction to a screw joint part, and a top cover is provided. Rotation in the direction of opening. In this case, the rotation in the direction of opening the upper lid rotates in the direction in which the fastening of the screw engaging portion is loosened, while the first and second screw members are screwed in the direction in which the fastening by screwing proceeds with each other. . As a result, the opening scheduled portion is pulled upward to form an opening, and the inner plug as the inner plug is opened or opened.

Moreover, as another aspect of this invention, a separation part is an inner seal stopper which can close an opening part after opening. In this case, since the separation part functions as an inner seal stopper after opening, liquid leakage becomes difficult even after opening, thereby forming a sealed space in which the sanitary state is maintained.

Moreover, as another aspect of this invention, the upper lid has a holding means which engages with the said separation part, when separating a separation part with rotational operation of a screw coupling part. In this case, since the separation part separated at the time of opening is held by the upper lid, the separation part does not fall into the container main body after opening the fastener, and there is no need to dispose of the separation part.

Moreover, as another aspect of this invention, a separation part engages with a holding means at the time of the opening operation | movement for formation of an opening part. In this case, since the separating part and the holding means engage with each other when opening the stopper, that is, during the opening operation for forming the opening, for example, the separating part and the holding means need to be welded in advance to form the opening. There is no.

In addition, as another aspect of the present invention, the upper lid is connected to the mounting portion engaged with the periphery or the container body, and connected to the mounting portion through the hinge portion, and in a closed state covering the opening after opening and opening the opening. Has openable lid In this case, after opening the plug, the opening and closing operation such as opening or closing of the cap can be easily performed with one touch by the opening and closing lid.

Moreover, as another aspect of this invention, an inner plug has a top opening closed by the separation part in the center, is continuously formed in a separation part in the said upper opening, and has a main body part which hangs on a container main body at the circumferential edge, The main body part has a main body side normal part that partitions the upper opening, and the separation part has a separation part side normal part which is offset to either one of the inner diameter side and the outer diameter side with respect to the main body side normal part. In this case, after separating the separating part from the main body at the time of first opening, and again, when the upper lid is twisted into the container main body, the separating part and the main body side normal part are fitted so as to overlap, whereby the separating part and the main body even after opening. Negative liquid sealing can be achieved. In short, liquid leakage when the upper lid after opening is closed can be prevented.

Further, as still another aspect of the present invention, the inner plug forms an airtight space by integrally molding the separating portion and the main body portion to be removed. In this case, since the separating part is removed from the integrally formed separating part and the main body part, the fastener is opened, so that the sanitary state inside the sealed space until immediately before opening can be maintained.

Moreover, as another aspect of this invention, a separation part has a flange in the upper part, the holding means has the protrusion which extends downward from the lower surface of the upper end wall of an upper lid, and the hook which is formed in this protrusion and can be engaged with a flange. Have In this case, the separator is simply and securely held in the upper lid.

In the cap, the inner plug and the upper lid form an opening by allowing the opening scheduled portion to be separated from the inner plug in accordance with the rotation operation by the rotation operation of the screw engaging portion, so that the opening operation is relatively simple and reliable. I can do it. In addition, since the pull ring is not used at the time of opening, the situation in which the pull ring is broken and becomes unopenable does not occur. In addition, since it is not necessary to secure a size enough to fit a finger as in the case of using a pull ring, the design is not limited even as a small-diameter fastener. In addition, since the separating part separated at the time of opening is held by the upper lid, the separating part does not fall into the container body after opening, and furthermore, there is no need to dispose of the separating part. In addition to the above, in the cap, the opening / closing lid is connected to the mounting portion via the hinge portion, and the mounting portion is detached from the fastener with the rotational action of the screw coupling portion, and is attached to the container body by the screw coupling portion. Since it can be matched, the element which comprises a cap can be comprised integrally. In addition, after opening and closing the fastener, the opening / closing operation such as opening and closing of the cap can be easily performed with one touch by the opening and closing lid.

In addition, as another aspect of the present invention, the separating portion is engaged with the holding means in the opening operation for forming the opening. In this case, since the separating part and the holding means engage with each other during the opening operation for forming the opening, for example, the separating part and the holding means need not be welded in advance for forming the opening.

Moreover, as another aspect of this invention, an inner plug and an upper lid are integrally molded as one article. In this case, each component can be made integral and the whole cap can be integrally formed as one article.

Moreover, as another aspect of this invention, an opening / closing lid has a latching means for inhibiting the operation which opens a lid. In this case, the operation of opening the lid cannot be performed due to a malfunction or mischief before opening, thereby increasing the reliability of the sealing by the cap.

Moreover, as another aspect of this invention, a screw engagement part has a rotation inhibiting mechanism which enables rotation operation only to one direction, and inhibits rotation to another direction. In this case, since the rotation direction in the rotation operation can be made only in one direction by the rotation inhibiting mechanism, malfunction can be prevented.

Moreover, as another aspect of this invention, a screw engagement part makes the direction of the rotation operation for formation of an opening part the counterclockwise rotation direction. In this case, the first rotational direction for opening can be set as the counterclockwise rotational direction, thereby preventing malfunction.

Moreover, in order to solve the said subject, the container with a lid which concerns on this invention comprises (a) the bottle which comprises the container main body, and accommodates the liquid which is a content, and (b) the said any cap formed in the inlet part of a bottle. It is provided.

[First Embodiment]

BRIEF DESCRIPTION OF THE DRAWINGS It is partial sectional drawing of the container with a lid for demonstrating the wiring type composite cap which concerns on 1st Embodiment.

The cap 1 which concerns on this embodiment is resin-molded, is attached to the inlet part 50a of the container main body 50 which is a bottle, the fastener 2 which is a lid main body, and the overcap which is an upper lid (3) is provided. The cap 1 and the container body 50 serve as a container 100 with a lid for storing and storing a liquid. In addition, for the sake of simplicity, only the right half of the cap 1 is shown, but the left half also having the central axis AX symmetrically has the same structure as the right side.

The fastener 2 is an integrally molded article made of resin, and includes an opening scheduled portion 4, a fitting portion 5, and an ejection cylindrical portion 6. Here, the fitting part 5 and the spout cylinder part 6 comprise the main-body part of the fastener 2. The fastener 2 forms a sealed space in which the contents are sealed or hermetically sealed together with the container body 50 by wiring. Among the fasteners 2, the opening scheduled portion 4 is also a separating portion having a cylindrical appearance having a bottom face, and the opening of the fastener 2, that is, the first of the fastener 2 along the score 7. The opening predetermined portion 4 is cut out from the horizontal wall 8 formed on the inner circumferential side of the fitting portion 5 and cut out at the time of opening of the fitting portion 5 to form an opening by leaving the horizontal wall 8. Moreover, the internal thread 10a for screwing into the overcap 3 is formed in the inner surface of the side part 4b of the opening plan part 4 (it mentions later for details). The fitting part 5 is a fitting member for wiring by fitting the fastener 2 to the inlet part 50a of the container main body 50. The fitting portion 5 has an outer cylinder portion 5a tightly fixed to a wall around the inlet portion 50a of the container body 50 and an inner cylinder portion 5b tightly fixed to the inner wall of the inlet portion 50a. It is composed. Although the spout cylinder part 6 is cylindrical in general, it has the lip | rip 6a which the diameter increases to the upper part in the upper end part, and improves the liquid disconnection at the time of pouring the liquid in the container main body 50. As shown in FIG.

The overcap 3 is an integral molded article made of resin, and includes a side wall 3a, an upper end wall 3b, a connecting portion 3c, and a seal portion 3d. The side wall 3a and the top wall 3b form the dome-shaped external appearance, and protect the fastener 2 from external environments, such as dust and water. The connecting portion 3c serves as a retaining means for retaining the opening scheduled portion 4 separated from the inner lid 2 after opening of the inner lid 2 in a dome composed of the side wall 3a and the upper wall 3b. Has a role. The inner wall of the seal portion 3d is in close contact with the lip 6a of the upper end of the pouring cylinder 6. Thereby, the upper end part of the injection | pouring_out_cylinder part 6 is kept liquid-tight, and the content in the container main body 50 can be prevented from leaking to the outside in the state which attached the overcap 3, and the inner plug 2 The operation of opening and closing the power after opening is possible.

In the overcap 3, the female screw 11a and the male screw 10b are formed inside the side wall 3a and the outside of the connecting portion 3c, respectively. The female screw 11a formed in the side wall 3a is a screw coupling part paired with the male screw 11b which the inlet part 50a of the container main body 50 has in a side surface. By the screwing of the female screw 11a and the male screw 11b, the overcap 3 is fixed so that attachment or detachment of the inlet part 50a of the container main body 50 is possible. That is, the container main body 50 can be attached or detached by the forward / backward rotation operation of the overcap 3. On the other hand, the male screw 10b formed in the connecting portion 3c is a second screw member paired with the female screw 10a which is the first screw member formed in the opening scheduled portion 4. The male screw 10b is screwed with the female screw 10a in the opening direction of the overcap 3, that is, the counterclockwise rotation, and pulls out the opening plug 2 as if the opening scheduled portion 4 is pulled out. It is an opening means cut out from the opening and opening or opening the cap 1. Hereinafter, the opening will be described in more detail.

In the present embodiment, in particular, the pair of screws 10a and 10b as one screw coupling portion and the pair of screws 11a and 11b as the other screw engaging portion are in a reverse relationship with each other. In other words, for example, when the male screw 11b side is a right screw, the male screw 10b side is a left screw. Thereby, when the overcap 3 is turned to the opening direction (counterclockwise direction), the pair of screws 11a and 11b which are the right screws rotate in the unwinding direction, but the pair of screws 10a and 10b which are the left screws. Rotates in the opposite tightening direction. By this relationship, the female screw 10a, that is, the opening scheduled portion 4 moves above the paper surface of FIG. 1 at a rate larger than the movement of the overcap 3. In short, the opening scheduled portion 4 is rapidly pulled upward by the rotational operation in the opening direction of the overcap 3. The opening scheduled portion 4 after opening is held by the upper lid 3.

2 is a cross-sectional view showing a state where an opening, that is, an opening, of the cap 1 according to the present embodiment is made. As described above, the pair of screws 11a and 11b rotate in a direction in which the fastening by the screw coupling with each other is loosened by the rotational operation in the opening direction of the overcap 3, and the pair of screws ( 10a and 10b are rotated or screwed in the direction in which the fastening by screwing together advances. Thereby, while the overcap 3 raises gradually, the opening plan part 4 is pulled upwards rapidly, and the opening plan part 4 is fastened along the score 7 which becomes a thin part like FIG. ) Is cut out from the spout cylinder 6 (see FIG. 2). The opening plug 2 is opened by the opening OP formed at the cut-out point.

In this case, by using the rotation operation of the overcap 3 having a large diameter, a large moment can be obtained even with a relatively small force, and the opening scheduled portion 4 is held by using a pair of screws 10a and 10b. You can get enough power to pull it out.

3A is a plan view of the fastener 2 viewed from above. Here, the outline OL is formed by the score 7 which is the thin part of FIG. In other words, the shape of the opening scheduled portion 4 of FIG. 1, that is, the opening OP of FIG. 2 corresponds to an area surrounded by the contour OL, and the area is the opening of the fastener 2 according to the present embodiment. Shape. In addition, although the shape of the outline OL is circular in FIG. 3A, the shape of the outline OL, ie, the opening shape, is not limited to this, One pair shown to FIG. 1 etc. in the area | region inside the outline OL. If the structure of the screws 10a and 10b of the can be formed, it can change suitably. For example, as shown in FIG. 3B, the shape of the contour OL may be oval. At this time, as shown in the figure, the screw structures 10a and 10b may be formed inside the contour OL similarly to FIG. 3A.

As described above, in the present embodiment, with the rotational operation in the opening direction of the overcap 3, the opening scheduled portion is performed by screwing in the direction in which the fastening of the pair of screws 10a and 10b proceeds as the opening means. Since (4) is cut out from the fastener 2, the opening of the cap 1, i.e., the opening plug 2, which is relatively simple in structure and accompanied by the rotational operation of the overcap 3, which is the upper lid, can be opened. By the screwing of the pair of screws 10a and 10b, the separated opening scheduled portion 4 is held by the upper lid 3.

In this case, the situation in which the pull ring is broken and the opening becomes impossible is not generated in the weld portion that may be generated at the time of opening by the pull ring. In addition, since the opening plug 2 is opened by the rotation operation of the overcap 3, it can be easily and reliably opened with a relatively small force. In addition, since the screw structure (specifically, the screws 10a, 10b, etc.) can be formed in the area occupied by the opening OP, for example, it is not necessary to secure a size that is enough to fit a finger. It can also be applied to the inner plug of, and the limitation of the cap 1 design can be avoided. In addition, since the opening scheduled portion 4 is integrated with the overcap 3 after the opening plug 2 is opened, the opening scheduled portion 4 does not need to be disposed of at a table without opening garbage after opening.

In addition, in this embodiment, the fastener 2 is a wire-type composite cap, and it is supposed that the contents are sealed or hermetically sealed together with the container main body 50 by wiring using the fitting portion 5. In addition, it is not limited to other wiring, For example, the liquid which is the content of the container main body 50 can be accommodated also according to the sealing by screw type or welding.

4 is a cross-sectional view for explaining a cap 101 according to a modification of the present embodiment. The cap 101 of this modification is resin-molded, and the member etc. of the code | symbol same as the code | symbol of the cap 1 shown in FIG. 1 etc. are the same as that of the cap 1 of FIG. .

In this modification, the over cap 103 further has the sleeve 9 which is a cutting member as an opening means. As shown in FIG. 4, the sleeve 9 has an annular protrusion shape falling from the lower surface of the upper wall 3b forming the vertex portion of the overcap 103, and the cross section of the lower end portion 9a is an acute angle. It has the edge part of the edge of, and touches or approaches the score 7 which becomes a thin part.

5 is a cross-sectional view showing an opening state by the cap 1 according to the present modification. In the case of this modification, in opening, the sleeve 9 moves upward with the opening operation of the overcap 103, that is, the counterclockwise rotation, but the movement thereof is larger than the displacement of the opening scheduled portion 4. small. As a result, the sleeve 9 acts to separate the horizontal wall 8 which is an outer side part of the score 7 downward from the opening scheduled portion 4. Therefore, in the case of the present modification, in addition to the action of the pair of screws 10a and 10b described in the present embodiment, the score (which is a thin part also depends on the action of the sleeve 9 accompanying the rise of the female screw 10a). 7) Power is added. Thereby, cutting of the opening plan part 4 can be performed more reliably. In addition, in this modification, the sleeve 9 has an annular protrusion shape, and the cross section of the lower end part 9a has a sharp edged edge part, The shape of the sleeve 9 is not limited to this.

In short, the separating part 704 is removed from the main body part 720.

In addition, with the rotation of the overcap 703 in the tightening direction, the score SC2 is cut, and the mounting portion 707 of the overcap 703 is detached from the fastener 702. At this time, the mounting portion 707 is engaged with the container main body 750 by screwing the female screw 11a and the male screw 11b.

As described above, after the opening operation of the fastener 702 is performed, the closed state of covering the opening OP of the cap 701 by the opening / closing lid 708 as shown in FIG. 18A, and FIG. 18B. As shown in FIG. 2, opening and closing of the opening OP is made possible. At this time, since the separating part 704 detached at the time of the opening operation of the fastener 702 is fitted to the protrusion 709 of the opening / closing lid 708, the separating part 704 is held in the opening / closing lid 708. It is. Therefore, the separating part 504 functions as an inner seal stopper which can close the opening OP after the opening plug 702 is opened.

In addition, in the said 6th embodiment, although the separating part side normal part 404b is offset by the thickness part of the main body side side normal part 706 inward rather than the main body side side normal part 406, the fastener 702 is shown, The side normal part 704b may be offset to the outside by the thickness of the main body side side normal part 706 than the main body side side normal part 706.

In addition, although the fastener 702 of the said 6th embodiment aims at the watertight or liquid-tightness between both normal parts by connecting the main body side normal part 706 and the separation part side normal part 704b with the score SC1, The score 707 is not necessarily required if the necessary watertight state, that is, the liquidtight state, is obtained by fitting the negative side normal part 704b to the main body side normal part 706.

Moreover, in the said 6th Embodiment, the seal which is an annular low protrusion can be formed in at least one of the outer peripheral surface of the separation part side normal part 704b, and the inner peripheral surface of the main body side normal part 706. By forming such a seal, a reliable liquid-tight state can be ensured between the separating part side normal part 704b and the main body side normal part 706. In short, liquid leakage can be reliably prevented during repeated reuse after the first opening.

In addition, about each hinge type cap mentioned above, in order to prevent opening operation | movement of a fastener, it is for suppressing operation | movement which opens lids, such as opening / closing lid 708 as shown to FIG. 19A, FIG. 19B, for example. A strip-shaped cover member CP may be used as the locking means. In other words, in this case, the opening / closing lid 708 cannot be opened unless the cover member CP is pulled off in the direction of the arrow in Fig. 19B, thereby preventing the opening of the lid due to malfunction or mischief before opening. Therefore, the reliability of sealing by a cap can be improved.

[Seventh Embodiment]

20A to 20H are views showing the structure and operation of the cap of the seventh embodiment. 20A to 20C are plan views illustrating the ceiling surface of the overcap. 20D to 20G are partial cross-sectional views for explaining the opening operation of the cap. In addition, FIG. 20H is a top view for demonstrating the virgin ring formed in the lower end of an overcap. The cap 801 of the present embodiment is resin-molded and includes, for example, a fastener 802, an overcap 803, and the like, as shown in FIG. 20D, but the virgin ring BR and the container body ( Except for the structure of 850, since it is the same as that of the cap 401 in 3rd Embodiment, detailed description is abbreviate | omitted. For example, as shown in FIG. 20A, on the ceiling surface of the overcap 803, the arrow and the number which show the rotation direction for showing a user's opening method are displayed. In addition, about this display, you may comprise in the ceiling surface of the overcap 403 similarly also in 3rd Embodiment.

Here, in the container main body 850 of this embodiment, as shown to FIG. 20D, along the outer surface of the bulging part 851, the some ratchet RT of projections is formed annularly at equal intervals. On the other hand, in the virgin ring BR of the cap 801, as shown in FIG. 20H, the annular ring BR of the cap 801 is annularly formed at regular intervals along the inner surface side at regular intervals. . Here, the ratchet RT and the hook NL form a ratchet structure. In other words, the cap 801 is hooked to the container body 850 in a state where the cap 801 is engaged with the ratchet RT by the hook NL of the virgin ring BR, and the cap 801 is closed by the ratchet structure. The rotation direction is limited to one direction at the time of opening the inner plug 802. Therefore, in this case, the ratchet RT and the hook NL function as a rotation inhibiting mechanism that defines the rotation direction in the rotation operation.

Hereinafter, the operation | movement of the opening of the cap 801 in this embodiment is demonstrated using FIG. 20E and 20F. First, in FIG. 20E, to detach the separating portion 804 of the fastener 802 from the main body portion 820, the overcap 803 is rotated in a tightening direction, that is, clockwise. Here, as mentioned above, because of the ratchet structure by the ratchet RT and the hook NL, the rotation of the overcap 803 is enabled only in the clockwise rotation direction. At this time, for example, the label attached to the side surface of the container body 850 has the intention of turning in the direction of the arrow marked with the number 1 for the first opening (not shown). By referring to this description, as shown in FIG. 20B, it can be recognized that the direction of the arrow FD indicating the clockwise direction among the arrow directions indicated by the overcap 803 is the rotation direction for the first opening.

As described above, when the over cap 803 is tightened, as shown in FIG. 20E, the virgin ring BR moves downward to move over the bulge portion 851 of the container body 850. At this time, the protrusion 809 is fitted to the flange 804d so that the separating part 804 is held on the overcap 803 side.

In addition, when the overcap 803 is tightened, as shown in FIG. 20F, the virgin ring BR completely rides over the bulge portion 851, and is separated from the overcap 803 to detach. At this time, the separating portion 804 of the fastener 802 is pushed downward, and the separating portion 804 is removed from the main body portion 820.

In this way, when the virgin ring BR is separated from the overcap 803, the rotation cap is not limited by the ratchet RT so that the overcap 803 can be rotated in the opposite direction from the time of opening. Will be. Here, as described above, in accordance with the description not shown by the user, this time by rotating in the direction of the arrow SD shown in FIG. 20C, as shown in FIG. 20G, the fastener 802 with the overcap 803 is shown. ) Is separated from the body portion 820. The fastener 802 is opened by two steps of operations corresponding to the arrows FD and SD as described above. In addition, the opening OP is formed as shown in FIG. 20G by this. In addition, when the overcap 803 is fixed again after opening, it returns to the state as shown in FIG. 20F, and the opening part OP is blocked by the separating part 804.

As described above, the ratchet RT of the container body 850 and the hook NL of the overcap 803 enable the rotational direction in the first rotational operation for opening only in one direction and the opposite. By making rotation impossible in the direction, the malfunction at the time of opening can be prevented. In addition, confusion of the user can be reduced by giving a display indicating the direction of rotation on the ceiling surface of the overcap 803. Moreover, the ratchet structure mentioned above can also be used similarly about the hinged cap shown in 5th Embodiment etc.

21A to 21E are views showing an example of a container with a lid using the cap 801 according to the present embodiment described above, and FIG. 21A is a partial cross-sectional view showing the fastener 802 of the cap 801. 21B is a figure which shows the container main body 850 of the cap 801, and FIGS. 21C-21E are the figures which show the container 1000 with a lid using the cap 801. As shown in FIG. The fastener 802 provided with the separating portion 804 shown in FIG. 21A, together with the container body 850 shown in FIG. 21B, forms a sealed space for enclosing a liquid that is a content contained in the container body 850. . The overcap 803 is attached to the container main body 850 in which the sealed space was formed, as shown to FIG. 21E. At this time, the overcap 803 is caught by the ratchet RT while the virgin ring BR is stopped at the immediately preceding position to be tightened. In the above state, the container 1000 with a lid before opening is comprised. Here, FIG. 21C is a figure which shows the container 1000 with a lid in the state after carrying out the initial opening of the cap 801 mentioned above. In other words, Figs. 21E and 21C show a state before and after the first opening of the cap 801, and Fig. 21D compares them. 21C to 21E, after the first opening, the overcap 803 is tightened to the sealed position where the overcap 803 is tightened by a clockwise twist for the first opening. The separating portion 804 of the cap 801 functions as an inner seal stopper that can close the opening after opening the inner plug 802.

22A to 22C are diagrams for explaining a modification of the present embodiment. In the present modification, as shown in Fig. 22B, the screw engaging portion constituted by the female screw 911a and the male screw 911b is a left screw opposite to the normal one. In other words, in this case, the direction of the rotational operation for forming the opening portion is the counterclockwise rotational direction. Therefore, as shown in FIG. 22C, the direction of the hook NL formed in the virgin ring BR is also in the opposite direction to the above-described case (see FIG. 20H), whereby the overcap 903 is formed by resin. The silver can rotate only in the counterclockwise rotation direction when the first operation at the time of opening is performed. In short, in this case, the overcap 903 is tightened by the counterclockwise rotation which becomes the operation | movement which opens a cap in a normal cap. For this reason, the display of the numbers 1 and 2 showing the procedure also differs from the case shown in FIG. 20A in the rotational directions of the arrows FD and SD shown in FIG. 22A. In this case, the rotational direction of the opening becomes the reverse direction to the rotational direction in the opening described above. As a result, the direction of the first rotational operation for opening can be made the counterclockwise rotational direction, thereby preventing malfunction. Moreover, also about the hinge cap shown in 5th Embodiment etc., the tightening rotation direction of a screw coupling part can be made into the counterclockwise rotation direction similarly.
